Abstract: Systems, methods and products for synchronization of content and metadata where the content and metadata are shared from a source repository to a target repository. One embodiment of a repository connector system utilizes a monolithic robotic server for scheduled synchronization and a second monolithic manual server for processing manual synchronization requests. A metadata server in the connector system enables sharing and synchronization of mapped metadata between content objects in the source and target repositories. A notification server is provided in the connector system to track notifications of changes to shared content in the target repository, and to replicate these notifications in a local database that is accessible by the synchronization servers to identify changes to the content in the second repository. Each of the servers is coupled to a service registry in the connector system to enable discovery and interaction between the connector system components.
